To change run levels, it looks like you need to login as "root" under RedHat. In there, there's the "SysV runlevel editor". You need to edit it to start run level 5. You might also have to edit /etc/inittab and change the "id" line so the second field is 5; there should be comments in the file. I'll send you a uuencoded tar file of my .fvwmrc, .xsession, .winenv-init, and some other files you'll need.
